NoLIbs is trying to reduce crime since the brutal murder of Sabina Rose O'Donnell in June.
A teenager grabbed a 16-year-old girl by her waist, showed her a handgun and told her to come with him, police said. She escaped without injury.
"The victim ran from the suspect and ran home where she called police," Stafford said.
The suspect was described as 5 feet 7 inches tall and weighed 200 pounds.
